HORAOE L. HAYDEN, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO HENRY O. GOODSPEED, OF SAME PLACE.

SPINNING RING AND TRAVELER.

SPECIFICATION forming part of Letters Patent No. 327,550, dated October 6, 188 5.

Application filed March 18, 1884. Serial No. 124,683.

To all whom it may concern:

Be it known that I, HORACE L. HAYDEN, of Boston, in the county of Sufiolk and State of Massachusetts, have invented a new and useful Improvement in Traveler-Rings for Twisting-Frames; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention is an improvement in travelers and traveler-rings for twisting-frames.

The object of my invention is, first, to render the friction of the yarn upon the traveler variable at pleasure within certain limits, whereby the twisted yarn may be wound more or less tightly upon the spool or bobbin. I have also sought to improve the construe tion of the ring and traveler in particulars hereinafter pointed out.

In the accompanying drawings, Figure 1 is a plan view of the ring. Fig. 2 is a side elevation of the inner part. Fig. 3 is a section through the two rings with the traveler in side elevation, and Fig. 4 is a view of the traveler detached.

The ringis composed of two partsan outer, A, and an inner, B. As shown, the inner part is a solid ring formed with an extension, a, to enter the rail, and a flange, b, to rest upon the top of the rail. The part c, extending above the rail, is formed with a shallow groove with a low curved rib above it, showing approximately an ogee curve. The outer ring has a bottom flange, f, adapted to rest upon the rail outside of the inner ring-flange, b. The bottom of the ring has a rabbet, g, to fit over flange b. The inner face of this outer ring is grooved, as shown at 2, Fig. 3, and the upper edge is slightly rounded. This ring is cut, as shown at 3, and each end has a lug, 4, and through the two lugs passes a screw, 5, by means of which the diameter of the ring may be increased or diminished. The two rings, when put together, as shown in Fig. 1, leave an annular race between them larger in its lower part, and adapted to receive and retain a traveler of suitable shape. The outer ring is held to the rail by screws in slots 6 6, these slots being inclined (No model.)

to allow the ring to move in contracting or expanding.

The improved traveler is shown at E. As ordinarily made these travelers are simple hooks or clasps of wire placed over and partially embracing the ring or flanges thereon. The friction of the yarn upon these travelers, as well as their friction on the ring, is invariable. To provide for the variation of the friction upon the yarn, I have made the traveler in the form of a solid block, and have set in the upper edge thereof a series of hooks, over one or more of which the yarn may be passed, according to the amount of friction required. I prefer to make the block or body of the traveler of brass, Babbitt metal, or similar material, and to make the hooks of hardened steel. The soft metal of the body does not wear the rings so rapidly as hard metal, and the steel hooks better resist the wear of the yarn, as the ordinary hooks composed of wire, when out by wear, tend to roughen the yarn.

It will be apparent that the expansion or contraction of the outer ring may be made to increase or diminish the friction upon the traveler. When the ring is expanded, only the shoulders or upper margins of the ribs 7 7 of the traveler will bear on the ring; but when the outer ring is contracted it may cause the grooved portions of the rings to bear on the whole surface of the sides of the traveler. The shape of the traveler is adapted to the faces of the rings for this purpose.

In operating this device the yarn is brought down in as many plies as may be desired, and passed under the hook or hooks, (increasing the number to increase the friction,) and thence the yarn passes directly to the spool in the ordinary way. In order to cause the traveler to lag, and thus to diminish the twist, I have only to turn up the screw and contract the outer ring.
